TITLE

Investigation of the Effect of a Synthetic Jet on the Heat Transfer Coefficient

pdf PDF

ABSTRACT

This paper deals with the experimental investigation of heat transfer coefficient (HTC) and continues authors’ previous research in a paper [1]. HTC is measured with using the thermoanemometry method on a heated plate on which impacts a synthetic jet. Those results are compared with HTC caused by impacted flow from a continual nozzle. The thermoanemometer works in a constant temperature mode for both cases of experiments, and a glue film probe placed on the heated wall is used as a measuring sensor.
